[gnuastro-commits] master 8d977a9 2/3: Avoid centering warning by Texinfo

[Mohammad Akhlaghi]

branch: master
commit 8d977a9b66f07a1b3a2fc70f7a6ec877afcaaa86
Author: Mohammad Akhlaghi <address@hidden>

    Avoid centering warning by Texinfo
    
    In the "Extending distance concepts to 3D", there were multiple instances
    of address@hidden' in the middle of a paragraph. This caused a warning by
    Texinfo on the fact that `center' must be at the start of the line. To
    correct it, all address@hidden's in this section now have their own 
paragraph
    (one empty line before and after them).
