patch: turned strings with backslashes into raw strings
In Python, the backslash in an unrecognized escape sequence is left
behind, which makes '\.' the same as r'\.'. Relying on this feature is
quite brittle, IMHO.
Removed unnecessary string concatenation as well.
#!/bin/sh
hg init
mkdir alpha
touch alpha/one
mkdir beta
touch beta/two
hg add alpha/one beta/two
hg ci -m "start" -d "1000000 0"
echo 1 > alpha/one
echo 2 > beta/two
echo EVERYTHING
hg diff --nodates
echo BETA ONLY
hg diff --nodates beta
echo INSIDE BETA
cd beta
hg diff --nodates .
