NAME
       unwrapdiff - demangle word-wrapped patches

SYNOPSIS
       unwrapdiff [-v] [file...]

       unwrapdiff {--help | --version}


DESCRIPTION
       unwrapdiff  demangles  patches  that have been word-wrapped, in an at-
       tempt 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 of 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.
