Bugzilla Bug 174547

When app-editors/nvi-1.81.5-r5 is built against sys-libs/db-4.3.29-r2, nvi has
problems reading long lines within files.  I ran across this when editing
/etc/make.conf.  nvi warned about not being able to read the long USE="blah
blah,etc." line, but my first keystroke was too quick and I didn't see the
warning until later when reproducing the issue.  I was able to skip past the
unreadable line, edit the part I want and then save.  Well, nvi truncated
everything after the example line:
#USE="X gtk gnome -alsa"

Effectively wiping out the /etc/make.conf!  Luckily I'm a good boy so I had a
backup from which to restore /etc/make.conf.

Revering to sys-libs/db-4.2.52-p4-r2, removing sys-libs/db-4.3* and rebuilding
nvi restores normal functionality.  I have reproduced this problem on (5) x86
machines.

Reproducible: Always

Steps to Reproduce:
1. emerge sys-libs/db-4.3*
2. rebuild app-editors/nvi

Actual Results:  
very bad awful things

Expected Results:  
editing files makes Gordon happy

Thanks for the report, and sorry for the inconvenience. Fixed now in 1.81.5-r6
(stable) and 1.81.5-r7 (~arch).

Thanks for the quick fix.  Manifest needs updating though for filesize mismatch
with nvi-1.81.5-r6.ebuild.

I'm not sure how that happened, but Tester_ fixed it before I got the chance to
check :)
