df54a266d3 indent(1): Remove an extra newline added in a previous commit. 
It doesn't math the remaining of the case statement.

b30bb755da indent(1): Optimize parser stack usage. 
When special else-if processing is enabled (-ei), we can assume "else if"
and "if" to be equivalent for indentation purposes.
This reduction saves a lot of stack space in case of a long "if-else-if
... else-if" sequence;  with this change,
Postgres/src/bin/psql/tab-complete.c as of 9.6beta3
requires minimum of the stack length to be 31 instead of 444.

16c2e36059 indent(1): add some comments to quiet down Coverity. 
Hopefully adding comments should help explain the code to both static
checkers and humans.

70a3049ea5 indent(1): Use a dash in the license headers. 
Use of the canonical dash avoids indent(1) from reformatting the
license headers.

5467ab90aa indent(1): Bail out if there's no more space on the parser stack. 
Also increase the stack size still keeping a conservative value of 256.
This is based on a similar changes done for PostgreSQL which instead
uses a stack size of 1000.

7916863d82 Make this compile cleanly when warnings are enabled: 
- 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()
