vim：加载文件后自动展开仅折叠在 .pm 文件中？
这是我的整个 .vimrc：
set ignorecase
set scs
let perl_fold=1
hi Folded cterm=bold ctermfg=yellow ctermbg=lightblue
set modeline
set hidden
加载 .pm 文件（通常只包含一个 package）时，该文件的所有代码都是折叠成一条线，我要做的第一件事就是展开折叠。
有没有办法让 vim 在加载文件后自动展开该折叠？我正在设想某种加载后钩子，它允许我判断整个文件（或超过 90%）是否折叠成一行，然后自动展开该折叠。 （如果文件开头有空行，则可能需要“超过 X %”条件，因为它们不会折叠。）
Here is my entire .vimrc:
set ignorecase
set scs
let perl_fold=1
hi Folded cterm=bold ctermfg=yellow ctermbg=lightblue
set modeline
set hidden
When loading a .pm file (which usually contains just a single package), all of the file's code is folded into a single line, and the first thing I have to do is to expand that fold.
Is there a way to have vim automatically expand that fold after loading the file? I em envisioning some sort of post-load hook which would allow me to say if the entire file (or more than 90%) is folded into a single line, then automatically expand that fold. (The "more than X %" condition might be needed if there are blank lines at the beginning of the file since they don't get folded.)
