Concatenate strings and identifiers into one string.
All other prefix, infix and postfix operators have lower priority than
``##``. For example, ``a1 ## a2~2`` is equivalent to ``(a1 ## a2)~2``.
For example::
[revsetalias]
issue(a1) = grep(r'\bissue[ :]?' ## a1 ## r'\b|\bbug\(' ## a1 ## r'\)')
``issue(1234)`` is equivalent to
``grep(r'\bissue[ :]?1234\b|\bbug\(1234\)')``
