[Python-Dev] pymigr: Ask for hgeol-checking hook.

[Neil Hodgson]

   Line end problems do occur in real projects. A scintilla-cocoa
project was branched off Scintilla to support the Cocoa GUI framework
on OS X. Here is one of the revisions in that project:
http://bazaar.launchpad.net/~mike-lischke/scintilla-cocoa/trunk/revision/5#include/ScintillaWidget.h

   If the ScintillaWidget.h changes aren't visible (after a brief
wait) then click on the arrow next to it. There are only 3 real
changed lines in this file (which are changing comments from C++ to C)
but the whole file appears to have been changed.

   This is far from the worst I have seen with some revisions showing
almost every line in a project changed.

   There are several effects from this:
1) The blame command loses usefulness as all lines in the file appear
to be from this revision.
2) Downloads become bigger, and take longer.
3) Fixing the issues takes time, effort and junks the history further.
