Ignoring config.h.in

[Martin Stjernholm, Roxen IS @ Pike developers forum]

Git status bothers me about untracked files:

# Untracked files:
#   (use "git add <file>..." to include in what will be committed)
#
#       src/modules/Gz/zlib_machine.h.in
#       src/modules/Pipe/config.h.in
#       src/modules/SANE/config.h.in
#       src/modules/_Image_GIF/config.h.in
#       src/modules/_Image_JPEG/config.h.in
#       src/modules/_Image_TIFF/config.h.in
#       src/modules/_Image_XFace/config.h.in
#       src/modules/_Regexp_PCRE/pcre_machine.h.in
#       src/post_modules/_ADT/config.h.in
#       src/post_modules/_Image_SVG/config.h.in

Turns out that the patterns for these files in .gitignore have
trailing whitespace, something cvs apparently ignored but git does
not.

It'd be nice if the conversion had taken care of this, but I guess the
only option now is to correct the patterns at the branch heads?
