Hi,

Currently, the Unix/_imagemagick, Unix/_graphicsmagic and X/_okular
completers only recognize .tiff, but not .tif, as the extension of a TIFF
file (the latter is common for files generated on Windows due to 8.3
filenames).  Compare with X/_{gqview,xv} which do recognize .tif as well.

I have checked that the underlying utilities do recognize .tif as an
extension, so could it be added to the respective completers?  Another
completer which may be enhanced is the `-exportlanguage` flag in `X/_xfig`
but I have not checked that xfig does actually suppport ".tif" instead of
".tiff".

Thanks,

Antony
