{if} statment problems on 3.1.24

[JercSi]

Example:

{if isset($abc.sub)
    and $abc.sub
    and isset($def)
    and $def and !isset($bla)}
{/if}

In 3.1.21 is template compiled without any problems

if (isset($_smarty_tpl->tpl_vars['abc']->value['sub'])&&$_smarty_tpl->tp...

In 3.1.24 looks like something breaks the compiling - && is missing:

if (isset($_smarty_tpl->tpl_vars['abc']->value['sub'])$_smarty_tpl->tpl_va....

Working examples on 3.1.21 and 3.1.24

{if isset($abc.sub) and $abc.sub and isset($def) and $def and !isset($bla)}{/if}

It also works if 'and' is replaced with &&

{if isset($abc.sub)
    && $abc.sub
    && isset($def)
    && $def and !isset($bla)}
{/if}

The lexer did not handle line breaks on the word logical operators like 'and' etc. it does work with the symbolic ones like '&&'.

The fix is already the the dev-master version.

We will soon release 3.1.25 as a maintenance release.
