Well, I can confirm on Windows that the behavior changed between 7.3 and
7.4. But I think this is a case of misunderstanding how ';' is supposed
to work. I was a little confused myself to begin with and tried the
exact same thing to see the failure!
Looking at :help file-searching, in the section on "upward search", it
took a little while, but eventually I understood that you put the "stop
directory" AFTER the ';', not before.
I think both you and the OP intended to use ';'.expand('$USER') instead
of the other way around.
Some experimentation shows that these work, on Vim 7.4, when the
directory is C:\Users\Ben\vimfiles\plugin:
:echo findfile('_viminfo', ';')
:echo findfile('_viminfo', ';Ben')
This does NOT work, it doesn't echo anything as the OP reported:
:echo findfile('_viminfo', 'Ben;')
All three of these work as intended in Vim 7.3 on Windows.
But, if I now understand ; properly, I think that 'Ben;' is actually
saying, "starting in the subdirectory Ben of the current directory,
search upwards". But here in vimfiles/plugin, there IS no subdirectory
called "Ben". So Vim is probably correct to fail.
';Ben', on the other hand, tells Vim "starting in the current directory,
seach upwards until you encounter the "Ben" directory. I think this is
what the OP intended.
