softlink and symlink are synonyms.

That's impossible.

[andrew myhost tmp]$ cd /tmp
[andrew myhost tmp]$ touch zzzz
[andrew myhost tmp]$ ls -l zzzz
-rw-r--r-- 1 andrew andrew 0 Jan  8 14:31 zzzz
[andrew myhost tmp]$ ln -s -f zzzz zzzz_symlink     
[andrew myhost tmp]$ ls -l zzz*
-rw-r--r-- 1 andrew andrew 0 Jan  8 14:31 zzzz
lrwxrwxrwx 1 andrew andrew 4 Jan  8 14:31 zzzz_symlink -> zzzz

For local file systems, MC gets nlink value directly from stat(2):
