[lttng-dev] [PATCH 2/2] doc: reformat long lines in doc/examples/Makefile.am

[Simon Marchi]

Format the long lines in the all-local target a bit like the "cmake"
target is formatted already.  I think it helps readability to have one
argument per line instead of very long lines.

At the same time, I removed the "cd .." at the end of parentheses.  The
parentheses start a new subshell, so it's unnecessary to do "cd .."
before the subshell exits.

I'm not too sure what's the best way to indent it, feel free to modify
it before changing the patch.
