Merge branch 'nd/shallow-deepen'
The existing "git fetch --depth=<n>" option was hard to use correctly when making the history of an existing shallow clone deeper. A new option, "--deepen=<n>", has been added to make this easier to use. "git clone" also learned "--shallow-since=<date>" and "--shallow-exclude=<tag>" options to make it easier to specify "I am interested only in the recent N months worth of history" and "Give me only the history since that version". * nd/shallow-deepen: (27 commits) fetch, upload-pack: --deepen=N extends shallow boundary by N commits upload-pack: add get_reachable_list() upload-pack: split check_unreachable() in two, prep for get_reachable_list() t5500, t5539: tests for shallow depth excluding a ref clone: define shallow clone boundary with --shallow-exclude fetch: define shallow boundary with --shallow-exclude upload-pack: support define shallow boundary by excluding revisions refs: add expand_ref() t5500, t5539: tests for shallow depth since a specific date clone: define shallow clone boundary based on time with --shallow-since fetch: define shallow boundary with --shallow-since upload-pack: add deepen-since to cut shallow repos based on time shallow.c: implement a generic shallow boundary finder based on rev-list fetch-pack: use a separate flag for fetch in deepening mode fetch-pack.c: mark strings for translating fetch-pack: use a common function for verbose printing fetch-pack: use skip_prefix() instead of starts_with() upload-pack: move rev-list code out of check_non_tip() upload-pack: make check_non_tip() clean things up on error upload-pack: tighten number parsing at "deepen" lines ...
