Same po string used for two different meanings

[jazzynico]

Build 20887 and 0.46 (stable).

In fr.po :

#. TRANSLATORS: "H" here stands for hue
#: ../src/widgets/toolbox.cpp:4279
msgid "H"
msgstr "T"

The same "H" is used for Hue, in Tweak tool (which is correct), and for Height, in the selector control bar.
The problem is that in French, the first H (Hue) is translated T (Teinte) and the second one H (Hauteur).

Seems to be quite old, maybe introduced with Tweak tool in 0.46.
