Bug#550288: custom verbatim environment problems despite PICTUREENV

[martin f krafft]

Package: latexdiff
Version: 0.5-2
Severity: normal

With the attached files, it seems that markup is being added inside
a custom verbatim environment causes troubles of all kinds, despite
my telling PICTUREENV to ignore the contents of the environment.

piper:/tmp% latexdiff --config 'PICTUREENV=(?:myverb)[\w\d*@]*' test1.tex test2.tex


WARNING: Inconsistency in length of input string and parsed string:
     This often indicates faulty or non-standard latex code.
     In many cases you can ignore this and the following warning messages.
