[Reportbug-maint] Bug#849123: reportbug: Tab autocompletion inefficient with large number of results.

[Taylor Kline]

Package: reportbug
Version: 6.6.6
Severity: minor

Hello,

Immediately upon launching reportbug, it prompts the user for a package name. Pressing <TAB> for autocompletion after typing 0 or very few characters results in an indefinite freeze of the reportbug package.

Contrast this with the behavior of apt:

$ sudo apt install <TAB>
<WAIT LESS THAN 1 SECOND>
Display all 52343 possibilities? (y or n)

reportbug should have this similar behavior rather than freezing.
