Bug#887299: tldr should depend on e2fsprogs explicitly

[Andrey Rahmatullin]

Control: reassign -1 src:haskell-shell-conduit/4.6.1-2
Control: retitle -1 Captures names of unrelated installed binaries at the build time

According to file it is a ELF 64-bit LSB executable, x86-64, version 1 (SYSV)
It's from libHSshell-conduit, and other haskell packages may have the same
false positive because of it.

Even better: /usr/share/doc/libghc-shell-conduit-doc/html/mini_Data-Conduit-Shell-PATH.html

It seems the package captures everything in $PATH or something like that and
generates functions (?) for all binaries it finds.

Of course this is very non-reproducible and potentially leaks interesting
things about the build system and at the same time I doubt this is useful
(though I don't understand how is it used).
