There is a function called StringBreak that you can override to do this.
(For some reason, this function was documented in version 2 but has been
dropped from the documentation in version 3).

StringBreak[n] is called to format the n'th line-breaking character in
a multiline output. So you can define

	Format[StringBreak[_]] := ""

to eliminate all the line-breaking characters.

A similar function, Continuation[n], is called to format the character
at the beginning of continued lines.  So, for example, the definition
Format[Continuation[n_]] := StringForm["(``)",n] would place a line
number inside of parentheses on the second and subsequent lines of
a multi-line output.
