[fortran, patch] Follow-up "widechar error" patch

[FX]

This patch fixes PR 52559 (http://gcc.gnu.org/bugzilla/show_bug.cgi?id=52559), which was due to my earlier patch for displaying error loci in lines containing wide characters (http://gcc.gnu.org/ml/fortran/2012-03/msg00015.html).

In preexisting code, a tab is displayed as a single space when an error is printed. I didn't handle it consistently, which should now be fixed.

Bootstrapped and regtested on x86_64-apple-darwin11. OK to commit?
