Shouldn't it be ^{!/... instead of ^{/!... ? People could have a
pattern starting with "!" and /! will change its meaning. On the other
hand, anything else after { is still reserved and can safely be used.

clarifies the above, I think.


Back then we seem to have been thinking only about ":" as the
overall "search the history to name an object traversing from all
tips" prefix, but the current one is described in terms of the more
generally useful "<committish>^{/<pattern>}" syntax and the escape
hatch applies--they are both handled by get_sha1_oneline() the same
way.
