description:
indent: give indent a try at formatting its own code

Formatting indent.h required the following manual corrections
afterwards:

The first tab in the comment in line 1 was replaced with a space but
shouldn't be.

The spacing around the '...' in function prototypes was completely
wrong.  It looked like 'const char *,...)__printflike', without any
spaces.

The '*' of the return type 'const char *' was tied to the function name,
even though this declaration was only for a single function.  In such a
case, it's more appropriate to line up the function names.

The function-like macros were not indented to -di.  This is something
that I would not expect from indent, so it's ok to do that manually.
