crlf normalization
r851 """ File system operations
Contains: Simple variants of normal unix shell commands (icp, imv, irm,
imkdir, igrep).
Some "otherwise handy" utils ('collect' for gathering files to
~/_ipython/collect, 'inote' for collecting single note lines to
~/_ipython/note.txt)
Mostly of use for bare windows installations where cygwin/equivalent is not
installed and you would otherwise need to deal with dos versions of the
commands (that e.g. don't understand / as path separator). These can
do some useful tricks on their own, though (like use 'mglob' patterns).
Not to be confused with ipipe commands (ils etc.) that also start with i.
