Split installation targets into install-bin and install-doc.
install-bin will only install the program, and install-doc will install
the documentation. The main install target still installs both.
#!/bin/sh
hg init
python -c 'print "confuse str.splitlines\nembedded\rnewline"' > a
hg ci -Ama -d '1 0'
echo clean diff >> a
hg ci -mb -d '2 0'
hg diff -r0 -r1
