Fixed.

Done.

Thank you very much: this is a very clear and useful explanation.

It happens 1) when you retrieve files from VCS systems or 2) when you
need to patch one of those files (it was required in a previous version
of the package).
I think the benefit to allow users developing peg/leg using the Debian
package sources does not compensate the trouble it gives to Debian
maintainers using a VCS.
I agree that a proper patch allowing peg/leg development and building
from scratch would be better, but I have no time for this.

Bests,
