check-code: expand sed rule to include more offenders Expands the rule added in 5e4491c114b2 to include cases where the address is a line number instead of a regular expression, and fixes an instance of this pattern in test-unionrepo.t.

check-code: add a rule against a GNU sed-ism BSD sed requires the 'i' command to be followed with a backslash and a newline, like so: $ sed -e '/^@/i\ > other' We've encountered this problem before, e.g. in test-mq.t (900767dfa80d). This change adds a check-code rule and fixes two instances of the problem in test-record.t.

color: set _colormode to None when mode is unset (issue3895) Previously, colorui assumed that it would only be called when mode wasn't None. 7ae12ce87594 changed that, so now colorui needs to care about whether it should colorize output.

color: turn colorui functions into forwards when color is None colorui will be set to None as necessary in an upcoming patch.
