help: do not abort topicmatch() because of unimportable extensions This is alternative workaround to D1198, originally spotted by the earlier version of the releasenotes extension.

configitems: register 'email.to' and 'patchbomb.to'

exchange: propagate the subfunctions return The parts generator can return a callback to handle server reply. We should propagate the return for correctness.

merge default into stable for code freeze # no-check-commit because default contains new vendored code

log: add an assertion about fctx not being None in patch.diff() As noted in the comment, this should not happen as removed files (the cause of fctx2 being None) are caught earlier.

log: handle removed files with --line-range patterns I.e. abort when the pattern corresponds to a removed file, as done with bare file patterns.

log: disable bare file patterns with --line-range Currently, specifying both a line-range pattern and a bare file pattern results in an AND operation whereas we probably want an OR so that bare file patterns are like a line-range pattern with all lines specified. So, until this works as expected, we disable this.
