[Bug-wget] [PATCH 3/3] Add command line option to disable use of .netrc

[Tomas Hozza]

Although internally code uses option for (not) reading .netrc for
credentials, it was not possible to turn this behavior off on command
line. Note that it was possible to turn it off using wgetrc.

Idea for this change came from Bruce Jerrick (address@hidden).
