Thanks @neykov and @geomacy - interesting!
I'm now not sure what is intuitive to a user!

FYI, my specific use-case is to write a yaml-test using `TestSshCommand`
that checks for the presence of particular lines in a log file. The command I
execute will grep the log, and then I want to assert that a couple of lines are
present in the stdout (I use a a regex to try to match the pattern on each
line).
I also had in the back of my mind someone using `TestSshCommand` to execute
a command and assert the stdout, but because of the `.bashrc` or whatever they
get extra stdout lines that they weren't expecting.
However, a power-user might well have a more complex regex, where they are
trying to match across multi-line output. If we start messing with the defaults
of DOTALL then it might well surprise them.

Looking at
http://stackoverflow.com/questions/3651725/match-multiline-text-using-regular-expression/3652402#3652402,
I wonder if what I want (for my use-case at least) is something like
`containsMatch: foo.*bar`. This would call `matcher.find()`.
@geomacy @neykov what do you think - shall I drop these changes and instead
add support for `containsMatch: ...`?
