got-build-regress.sh: build gotd too; ok stsp@

unbreak gotd build after recent change to got_pack_create

mention GOT_TEST_PACK=ref-delta in the README too

got-build-regress.sh: add another round of testing with ref-deltas ok stsp

regress: run gotadmin pack -D if $GOT_TEST_PACK=ref-delta ok stsp

gotadmin pack: add a -D flag to force using ref-delta Intended mostly for the regress suite, so we'll be able to test also the ref-delta code paths. ok stsp@

got-build-regress.sh: use -eq/-ne instead of ==/!= for numbers

regress: allow to run only a subset of the test cases This allows to run only the test cases named on the command line.

add -n to 'got commit' usage; patch by Josiah Frentsos

keep regress testname copypasta fix from 2a19e2e21a s/fetch_branch/fetch_honor_wt_conf_bflag so we don't report the wrong test in the case of failure. The incorrect testname was introduced in 1cb79834ea as the result of too much copypasta. It was subsequently fixed in 2a19e2e21a but then backed-out.

backout got: always fetch remote HEAD except when -b is used As pointed out by naddy, this behaviour is not ideal when users want to limit their repository to a particular branch which will diverge from HEAD over time, such as -stable branches. See https://marc.gameoftrees.org/mail/1676388048.8632_0.html

got: always fetch remote HEAD except when -b is used Rather than only fetch HEAD when there are no branches set in got.conf and there is no branch to be inferred from a work tree, or said branches don't exist on the server, always fetch HEAD unless 'got fetch -b branch' is used. ok stsp@

got.1: tweak commit -A description. ok jamsek

got: drop commit -A $GOT_AUTHOR restriction As discussed with op and stsp on irc, this prevents the valid case of changing a commit's author to yourself during a histedit operation, and potentially blocks other valid use cases too. ok stsp@ and op@

got/tog/gotadmin: pledge earlier In the case of tog move setlocale(3) before pledge(2), as suggested by stsp. ok stsp@
