check-code: centralize rules depending on implementation of repquote This decreases the cost of checking which regexp should be adjusted at change of repquote().

check-code: use fixedmap for replacement of space characters This can centralize management of fixed replacement into fixedmap.

check-code: replace quoted characters correctly 169cb9e47f8e tried to detect '.. note::' more exactly. But implementation of it seems not correct, because: - fromc.find(c) returns -1 for other than "." and ":" - tochr[-1] returns "q" for such characters, but - expected result for them is "o" This patch uses dict to manage replacement instead of replacing str.find() by str.index(), for improvement/refactoring in subsequent patches. Examination by fixedmap is placed just after examination for ' ' and '\n', because subsequent patch will integrate the latter into the former. This patch also changes regexp for 'string join across lines with no space' rule, and adds detailed test for it, because 169cb9e47f8e did: - make repquote() distinguish "." (as "p") and ":" (as "q") from others (as "o"), but - not change this regexp without any reason (in commit log, at least), even though this regexp depends on what "o" means This patch doesn't focuses on deciding whether "." and/or ":" should be followed by whitespace or not in translatable messages.

test-chg: add basic tests for server lifecycle I'm going to move around the codes in AutoExitMixIn. This test should catch a subtle bug of unlinking sockets which I made in draft patches.

test-chg: run only with chg It doesn't make sense to run test-chg.t without chg, so ignore it with vanilla hg, and specify chg executable explicitly. test-chg.t can host chg-specific tests.

distate: add assertions to backup functions Those assertions will prevent the backup functions from overwriting the dirstate file in case both: suffix and prefix are empty. (foozy suggested making that change and I agree with him)
