I failed to say one important thing (I was again fooled by the "it is too obvious to say" that led "gitcli" not to mention this, too). "dashed-options first and then args" rule means that generally we scan the command line from left to right one by one, and as long as the one we are looking at begins with "-", we try to interpret it as a dashed option, possibly eat the next one as an argument given to the option (e.g. "--abbrev 7"), and keep repeating, until the one we are at right now does not begin with "-". And then everything after that, we do not interpret it as an option. That is how "--heads" on the second example above, since we have seen . and took it as an argument (not a dashed option) is considered as a pattern. > ... > Apparently, it is not a common knowledge at least for you (and > probably others).
