To replace 'git rev-list' with 'git log' an important missing feature,
at least for me, is the support for '--stdin' option of 'git-rev-list'
that currently seems missing in 'git log'

I found this limit while trying to use 'git log' instead of 'git
rev-list'. The problem is that command line arguments could be very
long in some cases, typically when passing a list of sha's values (as
example all the branches sha). This happens of course when 'git log'
is run by script/applications not directly by the user.

Under Linux, command line arguments size limits are _normaly_ enough
(you could have problems for repository with hundreds of
tags/branches), but under *others* OS we are not so lucky.

So with '--stdin' you have an elegant solution to support any kind of
repository under any OS ignoring  the platform limit on command line
length.
