Merge branch 'js/trace2-raise-format-version'

2021-11-12T23:29:25Z

When we added a new event type to trace2 event stream, we forgot to raise the format version number, which has been corrected. * js/trace2-raise-format-version: trace2: increment event format version

trace2: increment event format version

2021-11-11T23:01:04Z

In 64bc752 (trace2: add trace2_child_ready() to report on background children, 2021-09-20), we added a new "child_ready" event. In Documentation/technical/api-trace2.txt, we promise that adding a new event type will result in incrementing the trace2 event format version number, but this was not done. Correct this in code & docs. Signed-off-by: Josh Steadmon Signed-off-by: Junio C Hamano

signature-format.txt: explain and illustrate multi-line headers

2021-10-13T02:06:24Z

A signature attached to a signed commit, and the contents of the commit that merged a signed tag, are both recorded as a value of an object header field as a multi-line value, and are subject to the formatting convention for multi-line values in the headers, with a leading SP signaling that the rest of the line is a continuation of the previous line. Most notably, an empty line in such a multi-line value would result in a line with a sole SP on it. Examples in the signature-format technical documentation include a few of these cases but we did not show these otherwise invisible SPs in the example. These trailing spaces cannot be seen on display or on paper, and forces the readers to look for them in their editors or pagers, even if we added them to the document. Extend the overview section to explain the multi-line value formatting and highlight these otherwise invisible SPs by inventing the "a dollar-sign at the end of line that appears after SP merely signals that there is a SP there, and the dollar-sign itself does not appear in the real file" notation, inspired by "cat -e" output, to help readers to learn exactly where such "a single SP that is originally an empty line" appears in the examples.
