Bug#1078251: latexdiff: (parcolumns incompatible) Text inside a \colchunk is ignored by diffing algorithm

[Manny]

Package: latexdiff
Version: 1.3.2-1
Severity: normal
Tags: upstream
X-Debbugs-Cc: tilmann at gfz-potsdam.de, debbug.latexdiff at sideload.33mail.com

Text inside the \colchunk command (which is used inside a parcolumns
environment) escapes the diffing algorithm. Text that is inside a
parcolumns environment but not in a colchunk is treated correctly. But
\colchunk is essential to the core functionality of parcolumns. A
minimal working example is attached.
