From: Teng Long <dyroneteng@xxxxxxxxx> Let's cleanup the unnecessary 'strbuf_grow' call in 'append_edit'. This "strbuf_grow(&d.buf, size + 1);" is prepared for insert a blank line if needed, but actually when inserting, "strbuf_insertstr(&d.buf, 0, "\n");" will do the "grow" for us. 348f199b (builtin-notes: Refactor handling of -F option to allow combining -m and -F, 2010-02-13) added these to mimic the code introduced by 2347fae5 (builtin-notes: Add "append" subcommand for appending to note objects, 2010-02-13) that reads in previous note before the message. And the resulting code with explicit sizing is carried to this day. In the context of reading an existing note in, exact sizing may have made sense, but because the resulting note needs cleansing with stripspace() when appending with this option, such an exact sizing does not buy us all that much in practice. It may help avoiding overallocation due to ALLOC_GROW() slop, but nobody can feed so many long messages for it to matter from the command line.
