This patch looks OK to me, so I'll apply it unless someone shouts.

Hallo Damon,

the --ignore-headers feature of gtkdoc-scan ignores
more than it should, namely:

- if I want to ignore g-cim.h, gtk-doc scan also ignores
  the whole g-cim subdirectory
- if I want to ignore test-blah.h, gtkdoc-scan also
  ignores blah.h

The reason is that \b in a perl regex defines a word characters
as "alphanumeric plus _".

A possible fix (I'm not a perl regex specialist, but it seems
to work):
