Bug#635984: [patch] Only create ~/.vim if netrw_dirhistmax > 0

[James McCoy]

Hi Charles,

NetRW provides g:netrw_dirhistmax as a way to prevent creating the
.netrwhist and .netrwbook files.  However, even when this variable is <=
0 NetRW will create the home directory to store these files.  The
attached patch changes this to only create the home directory if the
files are also going to be created.

Cheers,
