This adds fortran xfuncname and wordRegex patterns to the list of builtin

versions of fortran including 77, 90, 95.  The patterns can be enabled by
adding the diff=fortran attribute to the .gitattributes file for the
desired file glob.

The rest of your series looks reasonable, modulo the comments I posted
to individual patches. But I won't torture my eyes by trying to actually
see how well this matches fortran code, and just assume this is a good
change. :)

This also adds a new macro named iPATTERN which is just like the PATTERNS
macro except it sets the REG_ICASE flag so that case will be ignored.

Style nit: please keep macros all uppercase.
