From 359f0d754ab709c5a1ff3267bc117fb8559c62c2 Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Fri, 5 Feb 2021 14:44:48 +0000 Subject: range-diff/format-patch: handle commit ranges other than A..B In the `SPECIFYING RANGES` section of gitrevisions[7], two ways are described to specify commit ranges that `range-diff` does not yet accept: "^!" and "^-". Let's accept them, by parsing them via the revision machinery and looking for at least one interesting and one uninteresting revision in the resulting `pending` array. This also finally lets us reject arguments that _do_ contain `..` but are not actually ranges, e.g. `HEAD^{/do.. match this}`.
