Bug#941395: lintian: tries to do math on package version strings: Argument "1exp1" isn't numeric in addition (+)

[Thorsten Glaser]

Package: lintian
Version: 2.23.0
Severity: normal

[…]
N: Processing source package musescore (version 3.2.3+dfsg1-2, arch source) ...
Argument "1exp1" isn't numeric in addition (+) at 
/usr/share/lintian/checks/debian/changelog.pm line 211.
[…]

This is from the presence of…

musescore (3.2.3+dfsg1-1exp1) experimental; urgency=low

… as second entry in d/changelog. The “exp” clearly is a string part.
