commit 9870b80f81789d45744a6639d97c5f1595f9fd70
Author: Daniel Stenberg <address@hidden>
AuthorDate: Sat Jan 25 16:46:41 2020 +0100

    curl: make the -# spaceship bar not wrap the line
    
    The fixed-point math made us lose precision and thus a too high index
    value could be used for outputting the hashtags which could overwrite
    the newline.
    
    The fix increases the precision in the sine table (*100) and the
    associated position math.
    
    Reported-by: Andrew Potter
    Fixes #4849
    Closes #4850
