wrong way. Setup search only package names, not their content

Best with
https://cygwin.com/packages/
https://cygwin.com/cgi-bin2/package-grep.cgi?grep=col.exe&arch=x86

also with
$ cygcheck -p col.exe
Found 4 matches for col.exe
netpbm-10.61.02-1 - Toolkit for manipulation of graphic images
netpbm-debuginfo-10.61.02-1 - Debug information for Toolkit for 
manipulation of graphic images
util-linux-2.21.2-1 - Random collection of Linux utilities
util-linux-debuginfo-2.21.2-1 - Debug information for Random collection 
of Linux utilities

of course "col" is too short to be meaningful, "col.exe"
is a better catch.

util-linux is a popular package, so the issue was not yet noticed.

man was recently changed, so this dependency was likely missed,
specially as it seems hidden inside the man binary.
