Needless abbreviation of day names in certain locale in calendar

[snoyes]

In some languages (such as Malay), no weekday name is as long as 9 letters.

python -m calendar -L ms_my -e utf8 -w 9 2025 01 | head -2
                             Januari 2025
  Isnin     Selasa     Rabu     Khamis    Jumaat    Sabtu      Ahad

However, a text calendar will always abbreviate the day names if the width is set to less than 9:

python -m calendar -L ms_my -e utf8 -w 6 2025 01 | head -2
                  Januari 2025
 Isn    Sel    Rab    Kha    Jum    Sab    Ahd
