Coverity correctly reported that it's impossible for /comparison/ to be 0
here, because the only way for the for loop to end is by /comparison/
being < 0.
Fortunately the consequences of this bug weren't severe; for duplicated
entries in the typedef names file it would unnecessarily duplicate strings
with strdup(), but pointers to those would replace existing ones. So this
was a memory leak at worst.

Shift the responsibility of allocating memory for the string duplicate
from the caller (set_option, add_typedefs_from_file) to the callee
(add_typename) as it has more knowledge about when the duplication
actually needs to occur.

Add -sac (space after cast) and -nsac options.
These control whether space character is put after a cast operator or not.
Default is -nsac.
Add -U option for providing a file containing list of types.
This is needed for properly deciding which asterisks denote unary
operation and which denote binary.
These come from PostgreSQL.

strchr(3) returns a pointer not a boolean.
Attempt to make the style somewhat more ocnsistent with what indent
had before recent changes.

It seems that identifier "_t" is sometimes used as a variable name,
even in our tree. Not that I endorse that, but still it's better
to require at least one character before _t suffix to consider
an identifier to be a type name.

was mangled to "struct foo * bar". There should be an option to control
this, but no space is normal. This finishes fixing the bugs in rev.1.4.
indent(1) still doesn't really understand types in parameter lists. It
thinks keywords inside parentheses are for casts or sizeofs. This works
accidentally for scalar types and this quick fix makes it work similarly
but not so accidentally for struct/union/enum types.
the number of typedef-names is not so limited. Same as in rev.1.4.
Added the "const" and "volatile" to the keyword table. Rev.1.4 added
these but they were misclassified so they were not formatted as types.
indent still doesn't really understand them. E.g., it mangles
"char * const *foo" and "char *const *foo". This change mainly stops
it mangling "char const foo" to "char<declaration-indent>const foo".
properly. Of the 3 changes mentioned in the log message for rev.1.4,
the first (implementing -[n]fcb) was correct but didn't touch this
file, the second (no-space-after-sizeof) was not actually done (it is
the default and is controlled by the undcoumented -[n]bs options), and
the third (no-space-after 'struct foo *') was very buggy and was reduced
to wrong comments and other style bugs by backing out the main part
of it in rev.1.6. Rev.1.4 had 2 changes which were not mentioned in
its commit log: expand specials[] so that more than -83 typedef-names
can be specified (this was the one working change in rev.1.4), and add
"const" and "volatile" to specials[] (this was buggy).
2) Cast ifdef_level to a size_t before comparing it to a ratio of size_ts.
Ifdef_level should always be positive.
3) Complete prototype for chfont.
4) Cast some ptrdiff_ts to ints before using as a field width.
5) Avoid shadowing a local variable p with another local variable p.
- ANSIfy function declarations
- braces around initializers structs within structs
- add parens in complicated expressions
- disambiguate dangling elses
- no more implicit int
- make functions static where possible
- use prototypes
- don't use varargs hack for diag()
