wireproto: redirect the output earlier

wireproto: return in finally was messing with the return inside the block

tests: use a glob for all of the host, might not be localhost

commands: add move alias for the rename command svn provides move, and it's also a standard tool on Windows.

util: make wrap() require a width argument This keeps hgweb's help engine from poking at file descriptors that don't exist.

showconfig: don't accept multiple sections and one config item Showconfig now behaves as documented and only accepts one section.name argument or a number of section names.

hgweb: another fix for the help termwidth bug

pager: don't run pager if nothing is written to stdout/stderr This decides when to run the pager based on the first call to ui.write() and ui.write_err(). This has the side effect of not the output of subprocesses that write output before hg does.

pager: add global --pager=<auto/boolean> option

color: add global option in extsetup() instead of globally This prevents side effects from occurring when importing the color extension.
