The Bash works correctly in this case. Please have a look at Texinfo
documentation for the Bash. Bash separates (command line) input into
`words'. In this case the `words' are separated by IFS Bourne shell
variable.

CITE
`word'
     A sequence of characters treated as a unit by the shell.  Words
     may not include unquoted `metacharacters'.

...

If a word begins with an unquoted tilde character (`~'), all of the
characters up to the first unquoted slash (or all characters, if there
is no unquoted slash) are considered a TILDE-PREFIX.
EOCITE

In other words you need to have a character in the IFS variable
*before* the tilde character. IFS by default means whitespace
characters and a newline. Usually like the following.

   IFS=' \t\n'

To do what you want just write

   $ wget --post-file ~/vimrc www.example.com

or

   $ wget --post-file "~/vimrc" www.example.com
