[aur-general] Incorrect name when downloading from source=()

[Côme Pruvost]

Hello,

To package cellwriter, I need to download this patch[1]. But once
downloaded, the name of the file is
"attachment?aid=-5287197620305474653&name=cellwriter-1.3.4-cellwidget-dont-disable-xinput.diff"
instead of just
"cellwriter-1.3.4-cellwidget-dont-disable-xinput.diff".

- Is it a big problem ? I mean if another user do not use wget will my
PKGBUILD work for him ?
- Is there a way to force a correct behavior ?
