NAME
unwrapdiff - demangle word-wrapped patches
SYNOPSIS
unwrapdiff [-v] [file...]
unwrapdiff {[help] | [version]}
DESCRIPTION
unwrapdiff demangles patches that have been word-wrapped, in an attempt
to make them useful.
The corrected diff is sent to standard output. Note that you will
probably need to use the -l option when applying the patch, in order to
ignore any whitespace differences there may be.
OPTIONS
-v
Verbose operation. A list of lines that are modified in a way that
might be wrong is sent to stderr.
help
Display a short usage message.
version
Display the version number of unwrapdiff.
LIMITATIONS
Some heuristics are used to decide whether use a space to recombine a
wrapped line, or just join them together. Currently this is done by
comparing with last three characters of a line with the first two
characters of its continuation, and using a space if any of them are
different.
The patch needs to have been valid before being word-wrapped.
The last line of a hunk is nearly always ambiguous. If the next line
begins “@@”, “Index: ”, “diff ” or “- ” then it is taken to be
complete; otherwise it is unwrapped using the next line.
