Thanks everyone for the help.  Since i'm getting the path from the registry i
can't add in the extra backslashes without using sed.  I ended up with this
registy key which seems to work for local drives as well as network drives
(UNCs) (haven't tested files with special characters).

(manually typed into the registry)
C:\cygwin\bin\bash -v -c "/usr/bin/head \"$(/usr/bin/echo '%1' | /usr/bin/sed
's#^\\\\\(\w\)#\\\\\\\\\1#;s#\\\#\/#g')\" | /cygdrive/c/John/Tools/vim/gvim.exe
-R -" 

Here is the regfile if anyone wants to try it out.  You will prob need to change
your path to gvim, or just use the path to cygwin vim.

--START REGFILE---
Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\*\shell\Head2Vim]

[HKEY_CLASSES_ROOT\*\shell\Head2Vim\Command]
@="C:\\cygwin\\bin\\bash -v -c \"/usr/bin/head \\\"$(/usr/bin/echo '%1' |
/usr/bin/sed 's#^\\\\\\\\\\(\\w\\)#\\\\\\\\\\\\\\\\\\1#;s#\\\\\\#\\/#g')\\\" |
/cygdrive/c/John/Tools/vim/gvim.exe -R -\" "

--END REGFILE--
