Routine Description:
Force to wrap the last 'wrappable' part of the last line, if the last line
contains more than one 'wrappable' parts.
Arguments:
szLines - The result of WrapText, contains lines delimited by '\0'
iNumLine - Number of line in szLines
szOrigText - The original text that produces szLines, null-terminated
cchOrigText - Number of characters in szOrigText
Return Values:
szLines - if the last line contains more than one 'wrappable' parts,
szLines is modified.
