unwrapdiff - demangle word-wrapped patches
unwrapdiff [-v] [file...] unwrapdiff {--help | --version}
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.
-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.
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 dif- ferent. 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.
