Could X implementers please seriously consider limiting standard file names 
to some "reasonable" length?  Or at least, ensure that filename truncation
retains uniqueness?  I ask because HP-UX, HP's variant of System V, truncates 
file names at 14 characters.

A conflict occurs with the standard cursors, namely:

    sb_v_double_arrow.cursor
    sb_v_couble_arrow_mask.cursor
    sb_right_arrow.cursor
    sb_right_arrow_mask.cursor
    sb_h_double_arrow.cursor
    sb_h_double_arrow_mask.cursor

Equally meaningful equivalents which truncate uniquely are:

    sb_v_dbl_arrow.cursor
    sb_v_dbl_arrow_mask.cursor
    sb_r_arrow.cursor
    sb_r_arrow_mask.cursor
    sb_h_dbl_arrow.cursor
    sb_h_dbl_arrow_mask.cursor

Without some constraint on filename size, incompatibilities are bound to occur
with "portable" software packages (e.g., Ram Rao's X10 toolkit).
