the hook_line always print a line even if there is no content

[Pascal Poitras Dubois]

Describe the bug

the weechat_print modifier act as I expect, if you replace the string by nothing, no line is printed. However the hook_line doesn't work like that, it print a line with nothing. If this is the normal behavior can I have an explanation why it works like that?

Steps to reproduce

1. /trigger add test modifier weechat_print "" "/.*//"
2. /print -core test
3. /trigger addreplace test line core.weechat "" "/.*//"
4. /print -core test

Current behavior

for the weechat_print modifier, no line is printed, for the hook line a line is printed

Expected behavior

I expected the hook line to do the same as the weechat_print modifier

Hi,

This is the expected behavior: you must set buffer_name to empty string to remove the line.

The modifier has a different behavior.
