If this flag is directly followed by a `tt(k)' (`tt(K)'), `tt(m)'
(`tt(M)'), or `tt(p)' (`tt(P)') (e.g. `tt(Lk-50)') the check is performed
with kilobytes, megabytes, or blocks (of 512 bytes) instead. In this
case a file is regarded as "exactly" the size if the file size rounded up
to the next unit is equal to the test size. Hence `tt(*LPAR()Lm1+RPAR())'
matches files from 1 byte up to 1 Megabyte inclusive. Note also that
the set of files "less than" the test size only includes files that would
not match the equality test; hence `tt(*LPAR()Lm-1+RPAR())' only matches
files of zero size.
