bug#31765: 26.1; Can't define alias for git in eshell

[Carlos Pita]

Try

    alias g git

then

    g log

or whatever inside a git repo. It always show the git help page, as in a
faulty git invocation.

bug#31765: 26.1; Can't define alias for git in eshell

[Carlos Pita]

I found out that defining the alias as

   alias g 'git $*'

works. The documentation is unclear in this regard. See for example:

   https://www.gnu.org/software/emacs/manual/html_node/eshell/Aliases.html

It seems to imply that, like in bash, arguments following the alias
will be passed to the aliased command as usual.

bug#31765: 26.1; Can't define alias for git in eshell

[Carlos Pita]

By trial & error I came to the conclusion that the "juxtaposition"
case is not valid anymore. The example in the documentation:

     > For example, ll is a common alias for ls -l, and would be defined
     > with the command invocation ‘alias ll ls -l’; with this defined,
     > running ‘ll foo’ in Eshell will actually run ‘ls -l foo’.

plainly fails, it doesn't list foo but the current directory, foo is
simply ignored. The correct way seems to be:

     alias ll 'ls -l $*'

which is not documented (not even in the draft guide [1]).

Yes, this is documented in the Eshell manual, try

<f1> i g (eshell)Aliases RET

But the manual on the web doesn't seem to be updated.  Nicolas, I think
you've been updating the web manuals, right?

The manual on the web now seems to be updated.
