[TxMt] Latex bundle: error catching problem

[Alexander Ross]

Haris,

\xhh is the the character with hex value hh. So \x7f-\xff is the  
range of characters from \x7f to \xff.  Everything else in there is  
just regular expression syntax.  So, the reason that the regular  
expression doesn't match "./a-b.tex" is that the "-" character isn't  
matched in that regex.  I think there are probably other valid  
characters that aren't matched.
